Do I need Internet access to install and run Stream?

Yes. You will need Internet access to update and/or install Stream. Thereafter, a subscription plan to Stream will “call home” a few times a month to validate the subscription. No images are sent, but only a few bytes of data are sent to validate the subscription. So flakey, intermittent Internet is OK for the Stream Subscription License. If there is absolutely no Internet available at all, then you can go with a Perpetual License of Stream. Please contact us for more information about a Perpetual License for Stream.
